HP 900 GB SAS drive for enterprise servers

This 2.5-inch internal hard drive delivers 900 GB of storage with a 10000 RPM spindle speed. It connects through a SAS 6Gb/s interface for enterprise environments. The drive is suited for server workloads that demand consistent throughput and reliability. New condition, supplied in retail packaging.

SAS 6Gb/s interface determines compatibility

The drive uses a Serial Attached SCSI connection running at 6 Gb/s with a maximum external transfer rate of 600 MB/s. This interface is required by the host controller or backplane. Systems without a SAS 6Gb/s port cannot use this drive. Verify the interface before purchase.

900 GB capacity for high-I/O server roles

At 900 GB the drive holds operating systems, databases and active datasets in transaction-heavy workloads. The 10000 RPM speed supports low-latency random access for typical enterprise I/O patterns. Capacity runs out when data sets exceed the single-drive limit or when redundancy requires additional spindles.
